Dynamic Isolation Forest for Anomaly Detection in Post-PCI Myocardial Infarction Patients: Code and De-identified Development Cohort Data

This record contains the de-identified local development cohort data, analysis scripts, result tables, figures, and supporting documentation for the study “Dynamic Isolation Forest for Anomaly Detection in Post-PCI Myocardial Infarction Patients”. The dataset includes de-identified inpatient laboratory data from patients with myocardial infarction who underwent percutaneous coronary intervention (PCI). The accompanying scripts reproduce the fixed three-time-point window construction, feature extraction, model comparison, KNN-imputation sensitivity analysis, patient-level bootstrap stability analysis, and figure generation used in the local development cohort analysis. This release package includes:1. de-identified raw and processed development cohort data;2. fixed-window manifests and expert-review related data;3. Python scripts for preprocessing, model evaluation, sensitivity analyses, and bootstrap analyses;4. main and supplementary result tables;5. figures generated from the analysis scripts;6. documentation files, including README and data dictionary files. All direct patient identifiers have been removed before release. Dates and admission-related identifiers have been de-identified or transformed for privacy protection. The external MIMIC-IV supportive prognostic analysis is not included in this package.本数据集包含针对研究《用于PCI术后心肌梗死患者异常检测的动态孤立森林（Dynamic Isolation Forest）》的去标识化本地开发队列数据、分析脚本、结果表格、可视化图表及辅助文档。 本数据集涵盖接受经皮冠状动脉介入治疗（Percutaneous Coronary Intervention，PCI）的心肌梗死患者的去标识化住院实验室数据。配套脚本可复现本地开发队列分析中所使用的固定三时间窗口构建、特征提取、模型对比、KNN插补（KNN-imputation）敏感性分析、患者层面Bootstrap稳定性分析及图表生成流程。 本发布包包含以下内容：1. 去标识化的原始与处理后开发队列数据；2. 固定窗口清单及专家评审相关数据；3. 用于预处理、模型评估、敏感性分析及Bootstrap分析的Python脚本；4. 主要结果表格与补充结果表格；5. 由分析脚本生成的可视化图表；6. 文档文件，包含README文件与数据字典文件。 发布前已移除所有直接患者标识符。为保护隐私，所有日期及入院相关标识符均已做去标识化处理或转换。本发布包未包含外部MIMIC-IV辅助预后分析相关内容。
